Anyway to find resources on a map?

I just discovered steam power...but i need coal to build railroads. However, i cant find it anywhere after looking throughout the map. I traded territory and world maps with everyone but i still cant find it. Is there any search tool or technique that i cna use to find coal on the map?

If the game set it up (the map), and you haven't modded anything, then yes. It has to have all resources; one per Civ. To make the reaource easier to see; press ctrl-shft-m, while in game to clear map of overlays, you miht be able to see it better.
